Overview
These files are commonly termed as ‘ping' and they store the raster files using lossless compression. It came into existence in order to replace the GIF file format as they both have the ability to show transparent backgrounds. Furthermore, it was an enhanced and improved version of Graphics Interchange format. It supports different types of photos. The first one is palette-based photographs that can either have palettes of 24-bit RGB or 32-bit RGBA colours. Second is grayscale images which may or may not have an alpha channel for transparency. Lastly, there is a full-colour non-palette which is based on RGB/RGBA pictures. There is one limitation of this type. It does not support animation like GIF. Besides this, it is non-patented which means there are no copyright limitations.
Technical description
The expanded features like 8- bit channel for transparency and 24- bit RGB support make PNG more popular. The files stores in this format allow the fading of colours from opaque to transparent which is not present in the preceding format. CMYK does not offer support to this extension as it was developed for transferring of files over the internet, not for professional-quality print graphics. It stores information like textual comments, integrity checks and encoded basic pixels in its extensible structure of chunks. It always starts with an 8-byte signature followed by a series of chunks. A chunk furthermore comprises of four parts- length (4 bytes), chunk type (4 bytes), chunk data (length bytes) and CRC- Cyclic redundancy checksum or code (4 bytes).

Overview
An EPS file format is used for vector images in which points on a Cartesian plane are joined by lines and curves to form different shapes especially polygons. The added advantage to vector graphics is that they can be scaled up and down to any resolution. Emblems, figures, drawings, logos and other artworks can be saved using this format. Furthermore, it may have 2-dimensional vector graphics, text and bitmap images. As well as, a low-resolution image preview within the text document can be sent or received by an individual in it. One can also transfer the image between two or more operating systems, which makes it compatible format and that is why it is widely used by publishers. It is a standard format for storing both images and drawings within a postscript document.
Technical description
An EPS file has a Bounding Box DSC comment(the smallest enclosing box for a point set in infinite dimensions) which describes the rectangle that contains an image. This information can be used by the applications to configure or layout the page, even though they are not capable of directly rendering the Postscript inside. Resizing, editing and manipulation of the image can be done using different software like Corel Draw and Adobe Illustrator and there will be no effect on the quality. There are at least two necessary document structuring conventions(DSC) header comments and this adapts to Version 3.0 as well as to bounding box comment( it tells about the size of an image). There can be optional DSC comments. For instance, the %%Begin(End)Preview and it denotes the bitmap preview section.
